Hello Dev's!

I'm really new to OpenWrt and package building. Currently I'm trying to build serdisplib on a Debian Squeeze system with libusb support (to use a Megtron-LCD with lcd4linux) for my new Netgear WNDR3800.

I checked out OpenWrt Backfire (10.03.1) via SVN, selected the entries in menuconfig and built the toolchain and all dependencies. I modified the Makefile for serdisplib like that:

  DEPENDS:=+libusb

[...]

CONFIGURE_ARGS+= \
    --enable-shared \
    --enable-static \
    --enable-libusb \

If I try to {clean,compile} serdisplib I get this error:

[...]

serdisplib version: 1.97.9



supported extra libraries
=========================
 * libusb support            ... yes
 * libSDL support            ... disabled
 * libgd >= 2 support        ... no

If I try it directly with ./configure --with-libusb && make, it works without errors. But I can't build it for OpenWrt.

What's going wrong? Can someone help me to build serdisplib with libusb support? smile

Fixed! I added the global lib path ($(STAGING_DIR)/usr/include) to the build variables like this:

CFLAGS="$(TARGET_CFLAGS) -Wall -Wno-implicit -I../include -I.. -I$(STAGING_DIR)/usr/include" \

libgd is still disabled (don't know why), but libusb works with this change, I already tested it for some minutes at my WNDR3800 with a Megtron-LCD smile

Additionally I append a config item for libusb support. You can find my modified Makefile and new Config.in here: http://www.happytec.at/upload_files/ope … erdisplib/

And here is a ready-to-use binary for OpenWrt Backfire 10.03.1 for ar71xx - it's tagged with a new release number, ready to install with opkg: http://www.happytec.at/upload_files/ope … ar71xx.ipk

There's also an lcd4linux package with enabled serdisplib support (if needed): http://www.happytec.at/upload_files/ope … ar71xx.ipk

Maybe it'll help someone else to use his display at OpenWrt. I don't know if it's done the right way, but it works. It would be great if someone could validate it and send the changes to SVN. Thx.
